Solar power converted to energy

The sun is the source of solar power, When the sun heats water up, turning it into steam,
it starts a generator which produces electricity.Glass coverings on solar panels heat up because of the sun causing the water in black pipes underneath to heat up too. Solar cells help generate electricity. Another way solar energy is used is by a bunch of mirrors that are set in an angle to concentrate all solar energy into one place heating it up(temperatures can go up to 3000 degrees C in concentrated area). Solar energy is collected through thermal collectors and satelites.solar cookers are sometimes used to cook food but can take a long time.

How solar energy is used today

  • solar panels
  • solar calculator
  • solar cookers
  • solar fans
  • electricity for houses
  • satelites

Advantages of solar energy

Solar energy is good for the enviroment becase it doesnt contain greenhouse gasses or fossil fuels and there is no pollution. Solar energy reduces electric costs . Can be used to get electricity to sunny countries where there is no easy way to get electricity. Can be used for low powered uses such as a solar paneled garden.

Disadvantages of solar energy

Solar power doesnt work at night or doesnt work as well on cloudy days. It can be unreliable. Additionally, power stations and solar panels are very expensive to build or buy and ultimately cost more than they save.Solar energy works only in certain countires with sunny climates. Also it takes a lot of solar panels to power just one house.

Renewable or non-renewable

Solar energy is renewable because the sun can be used over and over again instead of just once.
